Do Brick Walls Absorb Moisture?

Since brick is porous, it will absorb any water that it comes in contact with. The brick is capable of keeping that water inside itself. But, if so much water is absorbed that the brick becomes saturated, then the water can actually flow through the brick.

Do bricks absorb moisture?

While bricks do absorb water, it is virtually impossible for wind-driven rain to be forced completely through a brick body. During the brick manufacturing process, high kiln temperatures fuse raw materials into a solid, water-resistant mass. Because of this, individual bricks do not leak.

Does brick absorb more moisture than concrete?

Concrete blocks are still prone to damage, but are more water resistant than clay bricks, meaning they won't be affected by rain, humidity, or sunlight the way brick might.
